Dexter Sani-Safe Boning Knives: This is my first season with these two boning knives--a 5-inch straight blade and 6-inch curved blade. In the past month, they've cut a bear, two antelope, and one deer. I've touched them up a few times, but for the most part the high-carbon steel blades stay sharp enough to bone and trim one deer-sized animal. I really like the handles, which are not only comfortable, but also clean up easily and are hi-viz white so I always know one is on the cutting table while I'm working with its mate. Best thing is, they are inexpensive. I picked these up at Cabela's for less than $20 each. Chances are, they're the same models your butcher uses.
